Steps to reproduce

1. Create a page on the demo author and set a title
2. Publish the page and confirm it exists on the public instance
3. Move back to author and open JCR app
4. Open the page created on the step 1, click on "Display system properties", select the Title attribute and delete it
5. Check that the page exists on the author instance but it has been totally removed from the public

Expected results

The property is removed on author instance only, the node has to be published to propagate the changes to public instances.

Actual results

The full page is deleted from the public instance

Workaround

N/A

Development notes

The original requirement:

The public instance gets updated by removing the title attribute from the modified page

changed to be the same as the behavior of the old framework.
